What dissection device is recommended for use in a patient with an implanted automatic internal defibrillator?

The ultrasonic dissector is recommended for use in a patient with an implanted automatic internal defibrillator due to its ability to separate tissue using high-frequency vibrations without generating excessive heat. This is particularly important in patients with defibrillators, as the use of devices that produce heat, like electrothermal bipolar and argon beam coagulators, may risk damaging the defibrillator or interfere with its function. Since the ultrasonic dissector minimizes thermal injury, it provides a safer option for dissection in the presence of such sensitive equipment. Additionally, using a laser coagulator could also pose risks of interfering with the device, making the ultrasonic approach the optimal choice for maintaining the integrity of the internal defibrillator while performing necessary procedures.
